Oracle Cloud Compute Common Terms and Usage

Oracle Cloud Compute offers a range of compute services and features for deploying and managing virtual machines and containers. Here are some key compute terms and their usage in Oracle Cloud:

Compute Instance: A compute instance is a virtual machine (VM) running in Oracle Cloud. Instances can be used for a wide range of workloads, including applications, databases, and web servers.

Availability Domain (AD): An availability domain is a physically separate data center within an Oracle Cloud region. Oracle Cloud regions consist of multiple availability domains to provide redundancy and high availability.

Virtual Machine (VM): A virtual machine is a software emulation of a physical computer, running an operating system and applications. Oracle Cloud offers various VM shapes (sizes) with different CPU and memory configurations to meet different performance needs.

Instance Shapes: Oracle Cloud provides a variety of instance shapes, each with specific CPU, memory, and network performance characteristics. Users can choose the appropriate shape based on their workload requirements.

Images: Images are pre-configured templates for creating instances. Oracle offers a range of standard images, including Oracle Linux, CentOS, Windows, and more. Users can also create custom images.

Orchestration: Oracle Cloud Compute allows you to create and manage instances using orchestration tools like Terraform and Oracle Cloud Infrastructure Resource Manager.

Instance Lifecycle: You can manage the lifecycle of instances, including provisioning, starting, stopping, restarting, and terminating (deleting) instances.

Load Balancers: Oracle Cloud provides load balancers to distribute incoming network traffic across multiple compute instances, ensuring high availability and scalability of applications.

Autonomous Database: Oracle Cloud offers Autonomous Database services, which are fully managed, self-driving databases designed for high performance, availability, and security.

Container Engine for Kubernetes (OKE): Oracle Cloud Container Engine for Kubernetes is a managed Kubernetes service that allows you to deploy, manage, and scale containerized applications using Kubernetes.

Bare Metal Compute: Oracle Cloud offers bare metal compute instances that provide direct access to physical hardware. These instances are suitable for high-performance workloads.

GPU Instances: Some Oracle Cloud instance shapes come with GPU (Graphics Processing Unit) options, which are suitable for AI/ML workloads and other GPU-intensive tasks.

Instance Console Connection: You can access the console of a running instance for troubleshooting and management tasks. Console connections are available for both Windows and Linux instances.

Instance Metadata: Instances can retrieve metadata about themselves using instance metadata. This can be useful for scripting and automation.

Instance Storage: Instances in Oracle Cloud come with local storage for temporary data. Additionally, you can attach block volumes or use file storage for persistent data.

Custom Images: You can create custom images from your running instances or imported images, allowing you to capture a snapshot of your VM's configuration and use it to create new instances.

Instance Networking: You can configure network-related settings for your instances, including assigning public and private IP addresses, configuring security groups, and defining network security rules.

Instance Scaling: Oracle Cloud provides tools for automatically scaling instances based on workload demand, such as Auto Scaling and Instance Pools.

These are some of the key compute terms and their usage in Oracle Cloud. Oracle Cloud Compute services offer flexibility, scalability, and control for deploying and managing virtual machines and containers to meet a wide range of computing needs.
